Cheesemonger's Mac and Cheese

Preparation

1. Step 1

   Mix all cheeses. Set aside 1 cup for topping; cover and chill. Melt 4 tablespoons butter in large saucepan over medium heat. Add flour and stir until mixture turns golden brown, about 4 minutes. Add thyme and nutmeg. Gradually whisk in milk. Simmer until thickened and smooth, stirring often, about 4 minutes. Add cheeses from large bowl. Stir until melted and smooth.

   Step 2

   Melt 1 tablespoon butter in heavy large skillet over medium-high heat. Add breadcrumbs; toss. Stir until golden, about 2 minutes. Transfer to plate.

   Step 3

   Preheat oven to 375°F. Cook pasta in boiling salted water until tender but firm to bite. Drain. Transfer to large bowl. Pour cheese sauce over; toss. Divide among eight 1 1/4-cup custard cups. Sprinkle with 1 cup cheese. Place cups on rimmed baking sheet. DO AHEAD: Can be made 1 day ahead. Cover with foil; chill. Drizzle each with 1 teaspoon cream. Cover with foil; bake 15 minutes. Uncover. Sprinkle partially baked chilled or just assembled cups with breadcrumbs. Bake pasta until beginning to bubble and tops are golden, about 20 minutes.
